Steel Screw/Tightening Hex.Screw/Flange Nut
Hex nuts and screws, bolts, screws cooperate with each other to connect the fastening parts.
Among them, type 1 six nuts are the most widely used, and C-class nuts are used for machines, equipment or structures with rough surfaces and low precision requirements. Class A and CLASS B nuts are used on machines, equipment or structures with relatively smooth surfaces and high precision requirements. Type 2 hexagon nut thickness M thicker, often used for often need to assemble and disassemble occasions. The thickness of the hexagonal thin nut M is thinner, and it is used for the occasions where the surface space of the connected parts is limited.
